Others can answer that question, too ... :-) Normally temperatures gradually decrease and the tree has opportunity to shut down supplying nutrients to the leaves so they die and lose their chlorophyll, which reveals the color of the leaf without the chlorophyll. If it gets cold quickly, the tree will drop the leaves quickly before they have a chance to lose their chlorophyll. A strong wind helps in the process of getting the leaves off the trees.
